Abstract: The invention relates to a disposable container of fibrous board comprising a bottom (3) and an upward mantle (2) heat-sealed thereto. The material for both the bottom and the mantle is a polymer coated fibrous board, in which the coating covers at least the inner surfaces of the container. According to the invention the material comprises a fibrous board base (8) such as paperboard or cardboard, an extruded inner coating layer (9) of a blend of polyethylene (PE) and polypropylene (PP), and an extruded outer coating layer (10) of polypropylene-olefin copolymer (PP-c). The inner coating layer (9) secures adhesion with the board base (8) and the outer coating layer (10) is for liquid-proof heat-sealing between the bottom (3) and the mantle (2) of the container. The container is in particular a microwave ovenable cup or food tray.

Abstract: The invention concerns a fibrous-based oxygen barrier film, which comprises (i) a microfibrillated cellulose (MFC) film, (ii) an oxygen barrier polymer layer, (iii) an optional tie layer, and (iv) an outermost polyolefin layer. The invention even concerns a laminate, in which said multilayer film is combined with a fibrous paper or board base by means of an intermediate polyethylene layer. The oxygen barrier polymerlayer, which preferably is EVOH, and the polyolefin layer are brought by coextrusion onto the MFC film. The film and the laminate according to the invention aim at an improved oxygen barrier in high humidity conditions and have use in oxygen-sensitive food packaging.

Abstract: The invention provides a biodegradable packaging material, a method of manufacturing the same, as well as products made of the material. There is coextruded onto a fibrous substrate (1) a multilayer coating comprising innermost and outermost layers (2, 4) of a blend comprising 20–95 wt-% of a higher melt index polylactide and 5–80 wt-% of another biodegradable polymer such as polybutylene succinate, and a middle layer (3) containing a lower melt index polylactide alone. The goal is to increase machine speed in coextrusion while maintaining good adhesiveness to the substrate and good heat-sealability of the coating. The products include disposable drinking cups and board trays, as well as sealed carton packages for solids and liquids.

Abstract: The invention provides a biodegradable packaging materi- al, a method of manufacturing the same, as well as products made of the material. The manufacture comprises extrusion onto a fibrous substrate (1) one or more polymer coating layers including at least one layer (2) of a polymer blend consisting of (i) 20–95 wt-% of polylactide having a high melt index of more than 35 g/10 min (210 °C; 2.16 kg), (ii) 5–80 wt-% of polybutylene succinate (PBS) or a biodegradable derivate thereof, and (iii) 0–5 wt-% of one or more polymeric additives. The components of the blend are melted and blended in connection with the extrusion step. The goal is to improve extrudability, increase ma- chine speed in extrusion and maintaining good adhesive- ness to the substrate and good heat-sealability of the coat- ing. The products include disposable drinking cups and board trays, as well as sealed carton packages for solids and liquids.
